The ultimate coaxial swerve/crab drive module, built using VEXpro components. The Revolution Pro 2 was designed and is distributed by 221 Robotic Systems (link takes you to external site).

• Features 3.25" VersaWheel DT and VEXpro gears
• 1.6:1 default final drive ratio (2.25:1 option available)
• Ships fully assembled for easy drivetrain implementation

The Single Reduction Clamping Gearbox achieves versatility through its simplicity. This gearbox uses four bolts to clamp onto a piece of 1" x 2" VersaFrame tube - no precision machining needed. Once mounted, it mounts a CIM-style motor offset from a bearing block on a perfect 84-tooth gear spacing. Use this efficient setup to drive an upper mechanism with ease, or combine multiple gearboxes to create a smooth-running, lightweight VersaChassis.

• Simple design for quick assembly and maintenance
• Variety of gearing options
• Combines with the Plastic Bearing Block for a second stage reduction

The CIM-ile gives teams the ability to emulate the RPM and mounting pattern of the popular CIM motor using two smaller motors in a compact, lightweight package. The precision VEXpro gears and glass-filled nylon housing create a system that is “similar” to a CIM and can be used with any gearbox or drive where a CIM would be used.

• Accepts RS-550 or 775 Series motors
• Single spur reduction to minimize size and weight
• Can be used anywhere a CIM would be used

Modular planetary gearbox system designed specifically for use by FIRST ^® Robotics Competition teams. The easiest way to put power where you need it in your design.
